IMPROVEMENT IN STEAM-HEATERS.

Specification forming part of Letters Patent No. 150,155, dated April 28, 1874; application filed April 8,1874.

Toall whom it may concern:

Be it known that I, CLINTON HART,- of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and Improved Steam-Heater, of which the following is a full and complete description, reference being had to the accompanying drawings making a part of this specification, in which Figures 1,2, and 3 are side views of the steam-heater. Fig. 4 is a view of the under side. Fig. 5 is a plan view.

Like letters of reference refer to like parts in the several views.

The object of this invention is for generating steam for heating and other purposes. Such invention consists of au arrangement of tubes surrounding the fireplace, and in which tubes are other tubes communicating with a water-space or jacket for the purpose of obtaining a circulation of water through the entire system of tubes.

The device is constructed and operated substantially in the manner as follows:

The heater or generator referred to consists of the shell or body A, which is of an oblong rectangular shape. To the body is attached a water-chamber, B, divided vertically into two compartment-s, C D, Fig. 2, by a partitionwall, E. The side of the water-chamber is represented as removed, in order that the partition and inside of the chamber may be seen. In the lower part of the body A is a fire-place, F, Fig. 2,'of which G is the door. The iiregrates are tubes H, Fig. 4, which figure repre sents an under-side view of the tire-place and grates. The front end of said grates open into the compartment C of the water-chamber, whereas the opposite ends of the tubes are sealed up water-tight. The sides and backsof the tire-place are lined with a series of tubes, I, Fig. 2, which represents the tubes only of one side ot' the nre-place. S aid side tubes are indicated by the dotted lines a, Fig. 3. The tubes on the back of the fire-place are parts of the side tubes, and are seen at J, Fig. 3, through the door G. Said tubes are also indicated by the dotted lines b, Fig. l. The end of the tubes surrounding the fireplace open into the compartment C, and so also do all the tubes K, Fig. 1, arranged in order above them, as seen in said Fig. 1, through the door L. The ends of the tubes K, seen through the door L, are intended to be closed water tight, but are represented as being open, in order to show a small tube, c, inserted in each of the large tubes K; The ends of the small tubes c are not closed, but open into the large tubes near the ends thereof, as indicated by the dotted lines a, Figs. 2, 4, and 5. The opposite ends of the small tubes pass through the compartment C, and open directly into the compartment D, as will be seen in Fig. 2. The ends of the small tubes, as they appear, opening into compartment D, are shown in Fig. 3. A portion of the side of the heater is broken away, so that the tubes c and the partition E may be seen.

The practical operation of the heater is as follows: Water is admitted into the chambers C D at any desirable part of the bottom, as at the opening f, Fig. 2. The water passes directly from the compartment D into compartment C, through the openings indicated by the dotted lines 7L, Fig. 3, made in the lower end of the partition E also by ilowin g over the upper end of it, which, as will be observed, does not extend to the top of the chamber. l/Vater also flows into the small tubes c from the chamber D, from which it runs into the larger tubes K. rlhey are also charged with water from the compartment C, into which they open, as aforesaid. From this arrangement of the tubes and their connection to each other and with the water-chamber B, it will be seen that a free and direct communication is established between the several parts, all of which are made water-tight. The ends ofthe tubes K are closed by caps screwed thereon, or otherwise. Now, on building a ire in the furnace of the heater the water in the pipes becomes at once heated. In consequence of its expansion the cooler water from the compartment flows therefrom through the small tubes cinto the large ones, K, while the hotter water flows back into the compartment C, thereby estab lishing a steady and uniform current of water from the compartment D of the chamber B along the small tubes c, thence back along the larger tubes K into the compartment C of the chamber B, as above said. The large amount of heating-surface presented by the arrangement of the large tubes K soon causes the Water to rise to a high degree of heat, and by its free distribution throughout the entire heater makes the apparatus of large heating capacity for Wa 1lning rooms,or for other needful purposes. It will be observed that the arrangement of the tubes K, above the iirebox, is sueh that the heat, smoke, and gases arising therefrom to the chimney N cannot pass in direct courses between them, but that they are diverted from sueh courses by the alternating relation of the tubes in respect to each other. Hence there is no Waste of heat from the furnace, as it is deeoted from pipe to pipe in its Way among them to the ehim ney, while the steam is taken from the heater through the opening ed, Fig. 5, or from other convenient parts of the steam and water chamber.

What I claim as my invention, and desire to seeure by Letters Patent, is

rIhe herein-described heater, consisting of the Water-chamber B divided into two compartments, C D, by a partition-wall, E, tubes K, and tubes o, arranged in combination With said tubes K, as described, fireplace F, and shell or body A, all constructed and arranged in relation to each other substantially as set forth, and for the purpose specified.

CLINTON HART.
